The printer is connected to the rest of your computer with connecting hardware. If the connecting hardware such as connecting cords or connecting pins are damaged or not secure, then printer would be offline. Users facing the printer offline issue are recommended to check the connecting hardware and if the connecting hardware is found damaged, they would have to be repaired to solve the issues.

I had the same issue and searched ALL over the net for a solution and was thinking about returning the printer until I found this. It works, ALL of my computers are up and running with no issues at all. Just follow these instructions and you should be up and running in no time.
